Content Analysis

Zainab Somji 9 weeks exam Content Analysis 2th January 2009 Aim of the study The aim of this study is to observe the different signs and behaviors of aggression in specific news shows. These news shows included: Fox News Sunday, CBS Evening News, and The Situation Room. Thus, each news show was observed for any signs of aggressive behavior. The categories that were observed in each of these shows were those of verbal aggression such as threatening, hitting, cursing, yelling, throwing, pushing, and stabbing. Thus, each category was evaluated by the amount of aggression in each show, and analyzed. Introduction/literature review Aggression, by definition, is behavior that intentionally acquires to cause harm (psychological or physical), pain or any personal injury. It is also known as the cause of pain between two entities of the same species. Thus, the essential aspect of determining aggression is the intention of the doer. Sometimes, accidents occur, such as trying to walking down a narrow aisle and bumping into a person. This is not determined as aggression because the intention was never there. However, although intention is the most important factor, it is extremely hard to determine the intentions of individuals. Thus, the key is to examine and observe the behavior and look for types of behavior that cause harm or pain, by physical or verbal means. Physical acts

Content analysis of a magazine - Kerrang

Content analysis of a magazine The magazine that I am analysing is called 'KERRANG!'. When the magazine is first opened there is a contents page. This is very brief but explains what news; features, reviews and regulars are in this week's issue. This is laid out so it is very easy to read and it mentions everything included. The contents are written in a small, white font on a black background, this is to make the writing stand out and be easier for the reader to read. Also on the first page is the editor's column. This is column usually involves him either describing the content of the issue, or him answering a popular question that has been posted in. This is usually in a small box situated in the top right hand corner. This is not necessarily supposed to be read as it is written in very small, white copy. I think it is written this small as most people skip through the opening content page and just flick through the magazine. This page also has a very big picture of a famous artist and what page his/her interview is on. The layout for this page is very well done as all the contents are put in a straight vertical column in a medium sized font, which makes them very easy to find and read. The page is designed so that it is easy to read and to make it easier for the target audience to find what they are looking for. The first twelve pages are about news of live gigs and

Analysis of Sulphur Dioxide Content in Wine

EXPERIMENT ( 3 ) Topic : Analysis of Sulphur Dioxide Content in Wine Introduction : In the presence of atmospheric oxygen, the alcohol content of wine can be converted to ethanoic acid making the wines sour & unpalatable. Even small amount of air, over a period of time, can adversely affect wines. The problem can be minimized by the introduction of a suitable reductant which will preferentially react with oxygen. One such reductant is sulphur dioxide but because it is toxic & pungent in odour, limits are set on the amount of "free" sulphur dioxide allowed in wine. Most of the preservative present in wine is "fixed" in the form of NaHSO3. Although this can act as a source of sulphur dioxide, the actual amount of free sulphur dioxide is quite low. In this experiment, the amount of total available SO2 in the wine, irrespective of its actual form in the sample is determined. The method involves first the conversion of all SO2 into SO32-. Acidification of the solution then liberates all SO2 : SO32-(aq) + 2 H+(aq) --> SO2(aq) + H2O(l) SO2 is then titrated with iodine solution : SO2(aq) + I2(aq) + 2 H2O(l) --> 2 HI(aq) + H2SO4(aq) Chemicals : White wine (non-sparkling or non-carbonated), 1M NaOH , 2M H2SO4 , 0.005M I2 , KIO3 , Starch solution (freshly prepared) Procedures : 1. Determine, from the label, the volume of wine in a bottle. 2. Using a pipette,

Analysis of the content in Aspirin Tablet

) Title: V3 Analysis of the content in Aspirin Tablet 2) Aim/Objective: To find out the mass of aspirin in each tablet by using back titration 3) Theory In this experiment, hydrolysis and back titration are carried out to determine the mass of the active ingredient aspirin in each aspirin tablet to see if it is the same as that stated on the package. Hydrolysis is a chemical process in which a molecule is cleaved into two parts by the addition of a molecule of water. Since aspirin (2-ethanoylbenzoic acid) can be readily hydrolysed using sodium hydroxide, forming the sodium salts of two weak acids, ethanoic acid and 2-hydroxybenzoic acid, and a water molecule, excess sodium hydroxide is used to react with aspirin in a conical flask initially, as illustrated in the following series of equations: CH3COOC6H4COOH(aq) + NaOH(aq)› CH3COOC6H4COO -Na+(aq) + H2O(l) CH3COOC6H4COO -Na+ (aq) + H2O(l) ? HOC6H4COO-Na+ (aq) + CH3COOH(aq) CH3COOH(aq) + NaOH(aq) › CH3COO-Na+(aq) + H2O(l) Overall reaction: CH3COOC6H4COOH(aq) + 2NaOH(aq)›HOC6H4COO-Na+(aq) + CH3COO-Na+(aq) +H2O(l) The hydrolysis is performed on a Bunsen flame to speed up the reaction. The kinetic energy of molecules becomes greater with an increase in temperature, colliding with each other faster. After warming for at least 10 minutes, all the 2-ethanoylbenzoic acid in the conical flask has reacted with sodium

Analysis of the Nitrogen Content of Lawn Fertiliser

CHEMISTRY INVESTIGATION Analysis of the Nitrogen Content of Lawn Fertiliser Research Question: What is the percentage by mass of nitrogen (from the ammonium ion NH4+) in Bunnings Green Up brand of lawn fertilizer compared to the manufacturer's specification of 12.3%? Aim: To determine the percentage by mass of available nitrogen, present as the ammonium ion, in Bunnings Green Up brand of lawn fertiliser, then comparing it with the one specified by the manufacturer. Hypothesis: Since the ammonium ion (NH4+) present in fertilisers is a weak acid, it is hard to obtain an exact end point. Hence, back titration can be used to determine the percentage by mass composition of nitrogen in the fertiliser. To deduce the amount of nitrogen in ammonia, the NH4+ ion is reacted with an excess of NaOH, and the amount of unreacted NaOH found by titration with HCl is used to deduce the amount of NH4+ ion present by subtracting it from the initial amount of NaOH to find the amount that reacted with it. From this, the percentage by mass of nitrogen present in the fertiliser can be found and subsequently compared to the manufacturer's specification. It is hypothesized that the percentage by mass of nitrogen present in the fertiliser will be similar or close to that specified by the manufacturer (12.3%). Materials: * * 100 cm3 of 0.1 mol dm-3 NaOH * 100 cm3 of 0.1 mol dm-3 HCl * 1.5

The content analysis, which I preformed, is based on twenty magazine articles.

Sarah Pinsonneault Dr. Marcia Kovitz Content Analysis Due date: November 5th, 2002 The content analysis, which I preformed, is based on twenty magazine articles. The magazine articles were taken from two types of magazine. The first type of magazine used are, paintball magazine's which are published in Europe. The second type of magazine used is published for the male audience in mind (Maxim, FHM, etc.). The magazine ads were printed in 2001 to 2002. The purpose of advertising is to convince people that products are of use to them in one way or another. If people agree, they will buy them. Magazines offer a number of unique appeals: the chance for readers to study the benefits of an advertised product or service at their leisure and the fact that print ads can be referred to again and again. Gender plays a vital role in the representation of the familiar, the desirable and the "real" in popular media culture. As an integral part of this culture, the world of advertising plugs into gender representations in particular and often very interesting ways in order to locate its products within the world as perceived by its intended viewers. Several famous Hollywood actresses and performers have been seen on many magazine covers displaying their nipples and cleavages. Breast exposures by famous women have been used to get people's attention and ultimately, to persuade

To determine the content of vitamin C in commercial tablets using volumetric analysis

Experiment 2- Analysis of Commercial Vitamin C tablets Title: Analysis of Commercial Vitamin C Tablets Objectives: To determine the content of vitamin C in commercial tablets using volumetric analysis and compares it with the manufacturers' specifications. Introduction: Commercially available vitamin C (ascorbic acid [C6H8O6], molar mass = 176 g mol-1) tablets usually specify their vitamin C contents on their packages. In this experiment, a brand of commercial vitamin C tablet and its vitamin C content is to be determined and compared with the value stated on the package. Ascorbic acid reacts with iodine in acidic medium as above. However, due to the low solubility of iodine in water, the ascorbic acid is not titrated directly with iodine. The iodine required in the titration is generated in situ by the reaction between potassium iodate(V)(KIO3), potassium iodide (KI) and dilute sulphuric acid. KIO3(aq) + 5KI(aq) + 3H2SO4(aq) › 3I2(aq) + 3H2O(l) + 3K2SO4(aq) The iodine produced by the reaction reacts immediately with ascorbic acid. The excess iodine is then titrated by standardized sodium thiosulphate (Na2S2O3) solution. This technique is known as back titration. 2Na2S2O3(aq) + I2(aq) › Na2S4O6 (aq) + 2NaI (aq) Thus, the amount of iodine reacted with ascorbic acid can be determined. Procedures: A. Preparation of Standard Potassium Iodate(V) Solution . The mass

A content analysis of gun and gun violence references in fifty-cent lyrics

A content analysis of gun and gun violence references in fifty-cent lyrics. ABSTRACT This study examined the references to guns and gun violence in fifty cent songs on his breakthrough, mainstream success, 'Get rich or die trying'. Altogether over eighteen tracks, there were 84 references to gun violence. 45% of songs contained 5 or more separate references. This was compared to Kanye West's album 'The college dropout' which had only two references over 21 tracks. It should be noted that while 50 cents references were all very violent, the two references on Kanye West's album had an anti-gun message, and specifically anti -gun in the hip-hop music scene where violence is increasingly becoming a problem, perhaps in part to rappers like 50 Cent. The research showed why there is so much controversy surrounding 50 Cent and that the allegations of him being an irresponsible gun-toting role-model are not totally unfounded. The research only focused on one 50 cent album, and the way I measured what was a reference and what wasn't could be seen as vague or at least open for debate. However further research has been suggested. INTRODUCTION Recent growth in gun crime, and gun culture have turned attention to reasons behind this trend. Hip hop has always been an easy target for groups who say that the music scene exerts a negative influence over those who listen to it. Nearly
